Last year, we had dismissability for logged in users (which led to a smaller version of the banner which still included a thermometer), and no dismissability for users who are not logged in. This year, both logged in and logged out users can collapse the banner to a smaller version. Many Wikipedians have expressed annoyance at the size of the collapsed version, especially because it includes a bright red button.

I've asked Rand to work with the technology team towards a significantly smaller default collapsed version for logged in users (e.g. just showing the current amount and a plain link to donate, plus an expand link). But, in the absence of data showing whether or not the current collapsed version incentivizes donations by repeat viewers, we won't make it smaller for logged out users at this point.
